ELK elasticsearch 插件管理

插件能额外扩展elasticsearch功能，提供各类功能等等。有三种类型的插件：

1. java插件
   只包含JAR文件，必须在集群中每个节点上安装而且需要重启才能使插件生效。
2. 网站插件
   这类插件包含静态web内容，如js、css、html等等，可以直接从elasticsearch服务，如head插件。只需在一个节点上安装，不需要重启服务。可以通过下面的URL访问，如：http://node-ip:9200/_plugin/plugin_name
3. 混合插件
   顾名思义，就是包含上面两种的插件。

安装head插件

bin         /         plugin          install          mobz         /         elasticsearch         -         head

安装中文分词插件ik，请参加之前的文章。

安装Marvel插件

# bin/plugin install license


# bin/plugin install marvel-agent

这个插件已经集成到kibana上了，kibana内容后续再说，还需要在kibana上安装Marvel插件

# bin/kibana plugin --install elasticsearch/marvel/latest

Marvel是收费的，监控工具，推荐使用。2.0版本会报NullPointerException错误，还未找到解决方法。

查看已安装的插件

# ./bin/plugin  list

删除插件

# ./bin/plugin remove plugin_name

关于插件更多内容参见：https://www.elastic.co/guide/en/elasticsearch/plugins/2.0/index.html

elasticsearch的内容暂且更新这么多了，转到kibana上去了，目前这些内容够你摆弄ELK。后面再回过头来继续elasticsearch内容，如增删查改等等。
